Visual editor and <bootstrap_card> crashes.#51

Whenusing the <bootstrap_card> tag, whether in a template or plain in a page, the visual editor crashes with the error:
Exception caught: Typed property Parser::$mOutput must not be accessed before initialization

It still works when rendering the page, and the code editor works as well. A simple workaround is to create a template for the card yourself with content like:

<div class="card float-right" style="width: 20em;"><div class="card-header"><h4 class="card-title" style="margin-top:0;padding-top:0;">{{{header|Header}}}</h4></div><div id="bsc_card_0"><div class="card-body">
{{{content|<p>Content</p>}}}
</div></div></div>

Setup and configuration

  • MW version: 1.41.2
  • PHP: 8.1.29
  • DB (MySQL etc.): mariadb
  • Skin (version): Chameleon 4.0
  • Bootstrap: 4.5
  • BootstrapComponents: 5.0

Steps to reproduce the observation (recommendation is to use the sandbox):
Include a tag like

<bootstrap_card header="Header" style="width: 20em;" class="float-right">
<p>Content</p>
</bootstrap_card>

In a page, and use the visual editor.
